Lets start with the light source
Replacing the sun with an artificial source is the most important factor, without a good grow light all the other steps are meaningless.
Sure, the old way of growing indoors with an HID light works. The HID bulb has produced many great results, but, when considering “small scale” grow operations, the HID comes away with more cons then pros. It makes the process more complicated, expensive and dangerous. The articles are endless on the comparison between commerical led grow light strips and HID lights and many bad LED products have helped to keep the myth alive that LEDs don’t work.
What is the upside to using LEDs?
The electricity saved with led grow lights samsung is nice, the lifetime of the product is great, but one of the most important benefits is the low heat output. A huge hurdle to successful grow operations is controlling the air temperature within the grow room. Controlling the temperature is very easy with LEDs, where with HIDs, it is not. HID lamps are costly to run, have a short lifetime, are extremely inefficient which is why all the extra heat is created. The heat from an HID can easily start a fire, burn your plants and heat up the grow room so much that you need to spend more money on active AC cooling.

Here is a list of why you should use a quality grow lights for indoor plants:
1) lower energy consumption
2) long lifetime
3) physically more robust, resistant to shock
4) lower heat output
5) easier to focus the light
6) instant on/off
7) dimming available if necessary
8) safer product “class 1” no mercury
LIGHT:
In general, never use a knock-off or cheap LED product and be skeptical of any product that doesn’t divulge which brand of LED is being used – Always use name brand LEDs with a constant current source with proven reliability. One of the reasons for using LEDs is longevity, but not all LEDs are created equal and there are LED products with poor reliability and lifetime issues. So, don’t go half way and buy a cheap LED product that is likely to break – buy a name brand LED product that will last.

To preserve the weed grow lights and to guarantee they emit the most amount of light, a good heatsink is absolutely necessary. LEDs do create a manageable amount of heat, but if overlooked, excessive heat will burn holes in the LED and cause the lumen output to drop below adequate levels. LEDs have made extraordinary improvements over the past few years. Forward voltages have gone down, maximum drive currents have gone up, lumen output has gone up, and maximum running temperatures have gone up, but still optimizing the environment with heatsinks is mandatory.
